Sarough rugs are made in the Markazi province in northwestern Iran, woven in the village of Saruk and the city of Arak as well as the surrounding countryside. Saroughs are hand knotted on a vertical loom using warp and weft in cotton. The weft consists of two or sometimes three threads. In carpets made before 1915, the weft is pushed down hard against the knots, which made the carpets especially compact. The pile is of very good quality wool and is cut short. However, more recent pieces seem to have deeper piles. The Persian knot is used with a density of 160 to 400 knots per square inch. Size: 6'8" x 4'4"
